Call & SMS Webhooks

React to events as they happen

Register one URL for calls and one for messages under Settings → Private Integrations → Webhooks, or through the API. Zonitel sends a POST by default; you can choose PUT, PATCH, or GET and add authentication for your receiver.

Incoming call

Sent when a call comes in to one of your numbers. Includes caller_id_name, caller_id_number, and destination_number.

SMS received

Sent when a message arrives on one of your numbers. Includes the sender, recipient, message text, and any media URLs.

SMS status

Sent when a message you sent is sent, delivered, or fails, with the message ID so you can match it to your record.

HTTP 200 · 5s

Your endpoint must be HTTPS, publicly reachable, and return HTTP 200 within 5 seconds. Acknowledge first, process afterwards, and ignore repeats.

FAQ

Frequently asked questions

Everything you need to know about connecting Zonitel to your stack.

Can I connect Microsoft Outlook Calendar?▾

Available in Zonitel Office. Connect Microsoft 365 or Outlook.com: Outlook appointments block availability in Zonitel, and Zonitel bookings are copied to Outlook. Connect each calendar in Office → Calendars Config → Connections, then sign in with Microsoft and authorize calendar access.

What systems does Zonitel integrate with?▾

Zonitel integrates with WhatsApp Business API, Facebook Messenger, Instagram Direct, AI chatbot, live chat widget, GoHighLevel, Appointlet, QQCatalyst CRM, Google My Business Reviews, Google Calendar, Microsoft Outlook Calendar, Google Drive backup, and custom systems via REST API v3 and webhooks.

Does Zonitel have an open API?▾

Yes. With REST API v3, your software can send SMS and MMS, pull call history, download recordings and transcriptions, place calls from your CRM, and receive call and SMS webhooks. Create credentials in Settings → Private Integrations.

Does Zonitel integrate with GoHighLevel?▾

Yes. Connect a GoHighLevel location to import contacts when you start an import, show GHL details such as tags, source, and custom fields on incoming calls, and link calendars. GHL appointments show up in Zonitel within minutes, and bookings made in Zonitel can be created, moved, or cancelled in the linked GHL calendar. Contact import is not a continuous two-way sync.

Can incoming calls show customer details from my own systems?▾

Yes. In Settings → Customer Info, an administrator can turn on upcoming appointments and GoHighLevel CRM, or add a custom HTTPS lookup with its authentication and the fields to show. Each user then chooses which business numbers show the caller card.

Does Zonitel integrate with QQCatalyst?▾

Yes. Zonitel uploads your call recordings to QQCatalyst every hour and files them against the client. If the caller isn't in QQCatalyst yet, the contact is created automatically. Recording must be on for the extensions whose calls you want filed.

Can Zonitel connect to WhatsApp for business messaging?▾

Yes. Through the official WhatsApp Business API, Zonitel lets your team send and receive WhatsApp messages from the same inbox used for SMS, phone, and other channels.

How do webhook integrations work with Zonitel?▾

You register one HTTPS URL for calls and one for SMS, in the portal or through the API. Zonitel sends an event when a call comes in (caller name, caller number, and the number dialed) and when a message is sent, delivered, fails, or arrives. Your endpoint must return HTTP 200 within 5 seconds.

How is API usage billed?▾

Messages sent through the API are billed separately from your phone plan. Other costs depend on the integration and the other service, so ask us and we will tell you what applies to your account.

WhatsApp Messaging from Your Software

Send WhatsApp messages and approved templates from your own application through the Zonitel API.

Connect WhatsApp in Office first, then use a private integration to check readiness, choose a business number, and send. Use an approved template outside the conversation window. A successful send is not a delivery or read receipt.

Requires active WhatsApp access. API messaging and WhatsApp usage are billed separately.
